The MacBook Pro 15" packs a million pixels over the 13-inch models we've already torn down. Here's a preview of the tech we're expecting to find inside today:

15.4" LED-backlit Retina display with 2880 × 1800 resolution (220 dpi), P3 color gamut

2.6 GHz Skylake quad-core Intel Core i7 (Turbo Boost up to 3.5 GHz) with integrated Radeon Pro 450 with 2GB of GDDR5 memory

16 GB of 2133 MHz LPDDR3 onboard memory

256 GB PCIe-based onboard SSD (Configurable to 512 GB, 1 TB, or 2 TB SSD)

Four Thunderbolt 3 (USB-C) ports supporting charging, DisplayPort, Thunderbolt, USB 3.1 Gen 2

Touch Bar with integrated Touch ID sensor

Force Touch trackpad

Stack them if you have them. Here we have the MacBook Pro 13" layered on top of today's main attraction, the MacBook Pro 15"—and apart from the size difference, they appear near identical. We're itching to see how similar (or not) they are inside.

The MacBook Pro 15" identifies as model A1707, which fits nicely between the A1706 and A1708 from our previous two teardowns.

Just like the previous MBP line, there are long air intake vents under the left and right sides. If this computer is anything like its little brother, these vents should serve double-duty as speaker outlets.

Houston, we have lift-off! This teardown has achieved first stage separation.

On initial inspection, the 15" MBP looks ... like a scaled up version of the 13" model. We do notice a difference in the battery layout, but overall it's like looking at twins.

Look who we ran into again! The connector to nowhere.

We'd still rather see a removable/upgradeable SSD, particularly in a machine targeted at pros—but this way if your logic board bites the dust, there might at least be a chance of recovering your data with Apple's help. Keep making those backups though.

Removing the trackpad requires as little effort as it did with other two 2016 MBP models—we simply spin out thirteen T5 screws and the trackpad is ours.

And this one is a monster, nearly holding its own beside an iPad mini 2.

We're not surprised to find the same ICs on this trackpad as we did in both 13" MBPs. However, with the increased size, Apple had to add a second touch controller to digitize all that extra trackpad:

STMicroelectronics STM32F103VB ARM Cortex-M3 MCU

Broadcom BCM5976C1KUFBG Touch Controller x2

Maxim Integrated MAX11291ENX 24-Bit, 6-Channel Delta-Sigma ADC

Monolithic Power Systems MP24830 white LED driver

Bosch Sensortec BMA282 accelerometer

Texas Instruments TMP421 remote/local temperature sensor

Macronix MX25L2006EZUI-12G 2 Mb serial NOR flash memory

Maxim Integrated MAX9028 comparator

Moving right along, it's time to get this logic board out. It's a little wider in the middle, but shares the same mustachioed symmetry of its smaller sibling.

Pulling off the new-and-improved heat sink (again, screwed through the back of the logic board), exposes the CPU and GPU.

Time to take a gander at this octopus lobo and see what makes it the leader of the pack. Highlights include:

Intel Core i7-6700HQ 2.6 GHz (up to 3.5 GHz) quad-core processor

Micron MT52L1G32D4PG-093 4 GB LPDDR3 (four chips for 16 GB total)

Intel JHL6540 Thunderbolt 3 controller (one for each set of USB-C ports)

Intel SR2NH (likely a platform controller hub)

Texas Instruments CD3215C00 (labeled as Apple's T1 chip in their keynote; however, that does not appear to be true)

Here's a close up of that T1, er, TI chip?

Texas Instruments CD3215C00

We can't ID this guy, but it's in the same spot that Apple claim their T1 chip that powers the Touch Bar is.

Other chips jockeying for position on this side of the board:

Samsung K4E4E324EE-PGCF 512 MB LPDDR3 DRAM, likely with a custom Apple-made SSD controller layered beneath

Anxious to get a peek at the third take on Apple's reengineered thermal architecture, we free the fans from the four T3 screws securing them to the rear case.

And they come out hassle-free. No glue on this puppy!

This fan is also sporting completely different blades from the ones we previously encountered.

After recently struggling to free the strongly adhered battery in the 13" MacBook Pro with Touch Bar, we decided to let this battery remain glued in its home.

This 15" MacBook Pro has a similar speaker grille when compared to its smaller 13" counterpart. Most of the grille doesn't include full through-holes, prompting us to question why the dimples, Apple?

Survey says: weight savers so it goes faster when you put wheels on it.

After once again accidentally separating the digitizer from the OLED panel, we turn our tools to the LED display.

Two teardown engineers, an opening pick, X-Acto knife, isopropyl alcohol, a heat gun, and an iOpener all came to this OLED teardown party, but Apple's adhesive was still too much for our glue separation squad.

Layout for the win!
